ng-scrolltop v1.0.6

ng-scrolltop

scrolltop component monitors current Y position in a long page or element then if scrolled down enough, shows up a clickable, unobtrusive icon that scrolls to top smoothly:

<div class="longList">
  ...
</div>

<scrolltop></scrolltop>

Optional inputs

scrolltop icon will show in left bottom of the screen and have some default attributes' values that can be adjusted by providing optional inputs like:

<scrolltop 
  [bottom]="'55px'" 
  [background]="'green'" 
  [size]="'60px'" 
  [sizeInner]="'36'" 
  [fill]="'white'">
</scrolltop>

By default, the library will work with window object but if your page has a scrolling element, you can pass over the id of that element like [elementId]="'my-scrolling-div'" to let the library work with the element not window.

A Stackblitz demo is available to show the usage.
